The image resolution in dot-per-inch.

Member Data Documentation

size_t Celartem::DjVu::JB2Encoder::RegionRecognitionParams::colorThreshold

Color threshold in [0 255], which is used to determine whether two objects are considered to be in same group or not. Larger value accepts more objects in a same group.

size_t Celartem::DjVu::JB2Encoder::RegionRecognitionParams::distLongMax

Longer-side distance maximum. For R dpi, the default would be R/5.

size_t Celartem::DjVu::JB2Encoder::RegionRecognitionParams::distShortMax

Shorter-side distance maximum. For R dpi, the default would be R/12.5

size_t Celartem::DjVu::JB2Encoder::RegionRecognitionParams::noiseThreshold

Noise threshold in pixels. The objects smaller than the threshold considered to be noise. For R dpi, the default would be R/100.

size_t Celartem::DjVu::JB2Encoder::RegionRecognitionParams::overlapThreshold

Threshold to determine whether two group areas are overlapped each other.
